【Detailed ways】

To solve this problem, it can be considered that insulating protrusions are provided on the injection molded parts of the frame to separate the conductive portion 130 of the powder feeding roller and the conductive portion 140 of the developing roller. However, such an arrangement needs to modify the existing mold to a large extent in order to manufacture the corresponding lower frame 120, and at the same time, it also increases the man-hours for the workers to produce and assemble, which is not cost-effective. In addition, it is also conceivable to perform insulating treatment on the surfaces of the first transmission part 132 and the second transmission part 142 . However, since the conductive part 130 of the powder feeding roller and the conductive part 140 of the developing roller arranged on the same side are relatively small and need to be fixed by screws, the effect of training workers for trial production is not satisfactory, and the insulating coating is easily scratched. Therefore, in the present application, one of the first conveying part or the second conveying part is moved to the other of the two side walls at both ends of the process cartridge in the length direction, so as to solve the problem once and for all.
